Question

Find the indicated function and write its domain in interval notation.
m(x) = sq. root of x-4, n(x) = x - 2, (m o n)(x)=?

I got m(n(x)) = sq. root of x-2 but am unsure if -4 should be under the radicand or not.

Answer 1

If it is under the radicand, I would do the math of -2-4 to get -6?

Answer 2

For the interval notation, I am getting (- infinity, 2) U (2, infinity)
